COMBINED HEATING AND ILLUMINATING BURNER.

Specification of Letters Patent.

Patented Sept. 30,1913.

Application ledebruary 1, 1912. Serial No. 674,762.

To all whom it may concern:

Be it known that I, MORTIMER L. Packen, a citizen of theV United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and usefulV Improvements in Combined Heating and Illuminating Burners, of which the following is a specification.`

My invention relates to combined heating and illuminating burners and contemplates the provision of a structure of attachment of this nature which is'peouliarly formed to obtain a maximum degree of heat by the flame maintained and to vhave the continuous and automatic operation of the burner vsuch as to preclude oxidation of the light diffusing and reflect-ing and deflecting surfaces. In the attainment of this result, it is important that the heating effect be not sacrificed. I have taken care of this and at the same time I have utilized the normal heat of the burner to draw in a current of air which is so directed and diffused as to 4form a layer intermediate any reflecting and deflecting surfaces of the burner and the heating flame.

The tendency, therefore, is generally to deflect the flame downwardly or lif this is not done to form a layer of comparatively cold air between the deflect-ing surfaces and the flame as stated.

My invention may be embodied in a burner having an annular series of gas jets with a plurality of air passages having their outlets near the said gas jets and desirably at a point slightly above the same. The heat of the gas jets is desirably rendered e'ective to produce a natural draft ofthe air into the passages and the continued heating of the air inevitably causing the rising thereof' within the structure'of the burner, is such as to cause the volume of air issuing from the passages to spread into a thin layer above the heat waves emitted from the flames of the gas jets and just below the main deflecting and reflecting plate or element of the burner. The main reflecting and deflecting plate is desirably a portion of the hood structure mounted above the gas jets and although such hood is sufficiently perforated to support combustion, it nevertheless sutilciently incloses the gas jets and the llames produced thereby to receive the heat waves upon its vert-ical walls and radiate the heat therefrom into the room. Thus, the light produced is maintained .at a high standard while the heat radiation is still undiminished. Not only do these aperturesA assist 1n creating a proper draft, but they serve as a means of escape for a certain portion of the heat to prevent smothering of the flame. v The preferred embodiment of my invention is shown in the accompanying drawings, in which similar characters of reference designate corresponding parts, and in which* Y Figure 1 is a side elevation ofmy attachment, Fig. 2 is a section taken on line 2-2 of Fig. 1, and, Fig. 3 is a detail of a wall guard desirably utilized in connection with my improvement. In carrying out my invention, I provide a hood structure having a disk-like upper portion 1, the under Vsurface of which is preferably highly polished to serve both as a reflecting and deflecting surface 2, and a circular depending wall 3 preferably apertured as shown at 4 for a purpose to be hereinafter described.

Depending from the central disk-like format-ion 1 and secured thereto by lugs 5 is an annular or ring-shaped element 6 having aplurality of gas jets 7 formed therein and leading from an annular chamber 8. This annular chamber 8 is fed from a T-shaped passage comprised of the ducts 9 and 10 communicating at a cent-ral point with the vertically extending pipe 11. This vertically extending pipe 11 is externally threadedat its upper end and adapted to screw into an integral formation 12 upon such ring-shaped element. At its lower end the pipe 11 is likewise externally threaded and by means of such external threads supports la valve structure 13 comprising a body portion 14, a bracket yoke 15, an internally threaded bore 16 and an intersecting bore 17 within which operates a valve 18. The bracket yoke 15 is formed with `an annular shoulder 19 at its upper edge and upon such annular shoulder 19 there rests a tubular formation 21 which embraces the pipe 11 and is disposed in concentric relation thereto. This tubular formation 21 serves as an air feed leading to the space between the diametrical formation 12 of the ring member 6 and the inner periphery thereof.

In conjunction with my hood structure, I may utilize a swinging guard bracket comproper comprising a casting attached to but said casting whereby an air draft is created being spaced from said hood structure and between sa1d opening and said apertures. being formed with an annular chamber hav- In testimony whereof I afiX my signatureV ing radial gas outlet ports, a central gas in presence of two witnesses. supply pipe connected with said chamber, MORTIMER L. PACKER. said casting having an open top, and an air Witnesses:
